Anecdotally i never get tinnitus from aspirin and i have had upwards of 3g in a day (spread out).
Everyday i have 30g of gelatin, which is around 8-10g of glycine
Aspirin depletes glycine to form salicyluric acid for detox
Without enough glycine, this causes tinnitus, gut irritation..
It prevents depletion, protects the liver, stomach. Also balances out tryptophan, lowering serotonin, stress
Per 325mg aspirin, use 10g gelatin/3g glycine
